Thanks Grant, Mark & Dick
I knew I could get an answer.
I was playing around and found that if I pasted the map into my drafting program, it became very easy to draw exact concentric circles.

I can make a circular selection, but when I go to the Edit menu, Stroke is dimmed. What do I have to do to be able to stroke a selection?
Never mind. Apparently I need to be in a paint layer rather than a draw layer in order to stroke.
James,
How are you creating the circle? If you use the Elliptical Marquee tool as described in mgs 1 & 2, you should be able to stroke it. If you use the Custom Shape tool or the Ellipse tool (not the marquee tool) then you cannot stroke it directly from that layer. However you can with a few more steps:
1. Ctrl-click the shape layer created by the Custom Shape or Ellipse tool. The circle is now outlined by marching ants.
2. Create a new transparent layer above the shape layer (click the "Create a new layer" icon at the bottom of the Layers palette.
3. With the new layer selected, do the Stroke. This creates the circle which can now be moved and resized.
4. Delete the shape layer from step 1.
